Trevethan, a Berlin junior who was the top seed in Class M, capped his undefeated season with Berlin’s first state title in boys tennis, beating Sebastian Casellas of Weston 6-1, 6-4 to win the Class M championship Thursday afternoon at Yale’s Cullman-Heyman Tennis Center.

“It gave me a sense of confidence but also there was a little pressure on me that I hadn’t lost,” said Trevethan, who was 24-0. “I think it was a good mix. Glad it worked out today.”

The finals started outdoors on the Yale courts but rain forced the players to finish inside.

Last year, Trevethan advanced to the Class M finals, where he lost to Andrew Ilie of St. Joseph, 6-0, 6-0. But Ilie transferred to Trumbull and moved to Class LL, where he won the title Thursday.

So Trevethan got to face Casellas, whom he had beaten in last year’s semifinals, 6-4, 7-5.

“I won, but it was a lot closer than this,” Trevethan said. “He has a very good slice and it’s hard to get down on it and hit over and play aggressive against. That worked for him. And his serve is hard to stop.

“My forehand and backhand, all around ground strokes, that just helped me today.”

Trevethan beat Weston’s No. 3 singles player Grady Tarzian in the quarterfinals and Weston’s No. 2 player Matthew Sydney in the semifinals.

Berlin coach Rex Smith said that Trevethan, whose father Scott also played for him, had improved since last year.

“He became more aggressive,” Smith said. “He has shots that he didn’t have last year.”

Weston won the Class M team title and Avon was the runner-up. Alex Klein Wassink and Adam Ortiz of Joel Barlow won the doubles title, 6-2, 6-4 over Weston’s Reid Brostoff and Steven Dampf.

Hand Wins Class L Title

Robbie Israel played five hours of tennis (including a three-set semifinal) at the state tournament Wednesday, didn’t sleep much Wednesday night, then had a physics field trip to Lake Compounce Thursday morning. Then he had to play in the Class L doubles final with teammate Noah Gulla against Guilford’s Gianni Esposito and Sam Inchalik.

Naturally, it went to a tiebreaker.

But Israel and Gulla prevailed, winning 6-1, 0-6, 7-6 (8-6) to win the title. And their Tigers team won the Class L championship with 23 points. Darien was the runner-up with 20 points. Andrew Forchetti of Notre Dame-West Haven won the Class L individual title 6-4, 7-5 over Darien’s Bobby Neuner.

Hand went undefeated this season and won the SCC championship.

“We won the first set 6-1 but I knew it wasn’t going to be that easy,” said Israel, a senior captain. “We had to keep going.

“Ever since freshman year, this is what I wanted to do. We set the goals early this year and we thought we could pull it off and we did.”

Last year, Israel lost in the doubles quarterfinals with a different partner, Alexander Bueno. Hand finished as team runner-up to New Canaan.

“It’s a great feeling,” Hand coach Dawn Fagerquist said. “We worked hard all year. We went 20-0, which is unbelievable. I’m happy for the boys and I’m just riding on their coattails.”

Old Lyme Runner-Up In Class S

No. 1 seed Max Klomp of Housatonic beat Charles Shanks of Litchfield 6-3, 6-2 to win the Class S title and Litchfield won the Class S team title with 12 points. Old Lyme’s top-seeded team of Morgan Greenho and George Danes won the doubles title with a 6-3, 3-6, 6-4 victory over Patrick Markovics and Matthew Newfield of Morgan, and Old Lyme finished as runner-up in the team competition with 10 points.
